AHA Coding Clinic® for ICD-9 - 2005 Issue 4; VOLUME 3 NEW/REVISED CODES
Hip Replacement Implant Bearing Surfaces
Effective October 1, 2005 unique codes have been created to identify the different types of bearing surface materials used in hip prosthetic implants such as metal on polyethylene bearing surface (00.74), metal-on-metal bearing surface (00.75) and, ceramic-on-ceramic bearing surface (00.76).Codes 00.74, 00.75 and 00.76 should be assigned as additional procedures, if the specific type of bearing surface is known. These codes may be used for hip replacement procedures (81.51 and 81.52) or revision of hip replacement procedures (81.53, 00.70-00.73). Prior to the creation of these codes information...

Article Overview
This article is a coding-focused overview of hip replacement implant bearing surfaces and the procedure code changes that were introduced to distinguish different materials used in hip prostheses. It is relevant to inpatient coders, coding educators, orthopaedic surgery teams, and CDI staff who need to understand when the documentation supports reporting these procedure codes in hip replacement or revision scenarios. The article also provides general background on why bearing surface type matters for data capture and outcomes, along with a brief coding example at the end.
Why This Topic Matters
Accurate capture of hip implant bearing surface information affects procedure coding specificity and can improve the quality of outcome data for replacement and revision cases.
Article Sections
-
Effective October 1, 2005
Introduces the purpose of the new hip implant bearing surface procedure codes and the context for their creation. It also identifies the general types of hip procedures where the codes may apply.
-
Metal on Polyethylene (00.74)
Provides background on one of the bearing surface categories and the general clinical motivation for its development. The section discusses wear-related considerations at a high level.
-
Metal-on-Metal (00.75)
Summarizes another bearing surface category and its broad comparative characteristics. It also notes that longer-term effects were not yet fully established in the source content.
-
Ceramic-on-Ceramic (00.76)
Describes the third bearing surface category and its general material characteristics. The section focuses on broad performance and biologic properties.
-
New subcategory 00.7 Other hip procedures
Lists the new procedure code additions tied to hip replacement bearing surface reporting. This section serves as a concise code-centered summary of the introduced subcategory.
-
Clinical example and coding question
Presents a brief revision scenario involving a prior hip arthroplasty and asks how the case should be coded. The example is incomplete in the supplied text.
